Deserts are supposed to be hot. The Turan deserts freeze — hard, for months — then bake past forty in summer, and everything that lives in them has solved both problems at once. In 2023 UNESCO inscribed the Cold Winter Deserts of Turan across Kazakhstan, Turkmenistan and Uzbekistan: the first listing dedicated to this doubly extreme world.
The property strings more than a dozen protected areas across the Turan lowland, from the Aral Sea’s ghost shores to the sand seas of the Karakum and Kyzylkum. Our route takes three stops, one per country — Barsa-Kelmes in Kazakhstan, Repetek in Turkmenistan, and Uzbekistan’s Kyzylkum — a transect through a biome most travellers cross by night train without knowing it has a name.
What “cold winter desert” means
Continental position does it: too far from any ocean to be moderated, the Turan basins swing between Siberian winters and Iranian summers. Plants here endure frozen sand and drought in the same year — the saxaul tree, the biome’s keystone, does both while stabilising the dunes its forests grow on. The animal cast is correspondingly unusual: goitered gazelle, the resurrected kulan (Asiatic wild ass), monitor lizards at their northern limit, and the saiga antelope whose swollen nose filters dust in summer and warms air in winter — evolution’s answer to the same double problem.
Barsa-Kelmes: the island that stopped being one
Kazakhstan’s Barsa-Kelmes — the name translates, encouragingly, as “go and you won’t return” — was an island in the Aral Sea until the sea withdrew around it; the nature reserve, one of Central Asia’s oldest, now rises as a plateau from the dried seabed. It preserved kulan and saiga through the twentieth century precisely because it was unreachable, and its new surroundings — the Aralkum, the desert that used to be a sea — make it the starkest environmental parable on any World Heritage list.
Repetek: the sand laboratory
In Turkmenistan’s eastern Karakum, the Repetek reserve has been studying sand since 1927 — one of the oldest desert research stations anywhere. Its black saxaul forests are the finest in the biome, and its records of dune movement, extreme temperature and desert ecology span a century. The Trans-Caspian railway passes the station: for once, a strict reserve with a platform.
Kyzylkum: the red sands
Between the Amu Darya and Syr Darya spreads the Kyzylkum, the “red sand” — one of the great deserts of the world, whose protected sectors joined the 2023 listing. This is the desert Silk Road caravans actually crossed between Khiva and Bukhara, and the practical stop for most travellers: the yurt camps and lake of the Nurata foothills put saxaul steppe, dunes and desert nights within reach of the standard Uzbek circuit.
Planning the journey
Honesty about access: Barsa-Kelmes requires expedition logistics via Aralsk and reserve permission; Repetek depends on Turkmenistan’s visa regime, which is its own adventure; the Kyzylkum is the accessible third — yurt stays between Samarkand and Khiva can be booked from any Uzbek operator. Seasons are non-negotiable: April–May for flowering steppe and bearable temperatures, September–October for clear cool days; summer is dangerous and midwinter brutal, which is, after all, the listing’s entire point. Combine the Kyzylkum stop with our Zarafshan–Karakum Silk Road route — the desert is the road’s other half.
The saxaul economy
One tree runs this biome, and it deserves its close-up. Saxaul — black along the water tables, white on the open dunes — grows twisted, slow and iron-dense; its wood sinks in water and burns hot enough that caravans and railways stripped whole forests of it for fuel across the nineteenth and twentieth centuries. Its living value is greater: the roots bind moving sand, the canopy shelters seedlings of everything else, and the groves function as the desert’s oases-without-water, concentrating birds, gazelles and shade. Modern restoration programs across all three countries now plant saxaul by the million, including on the dried Aral seabed, where the belts are the main defence against the salt-dust storms the vanished sea exports.
The herding cultures of the Turan lowland built their seasonal rounds on the same plant — winter camps in the saxaul’s windbreak, camels browsing its shoots — and the listing’s cultural undertone is their mobility: the desert was never empty, only lightly and expertly inhabited. Learn to recognise the tree from the train window between Bukhara and Khiva and the “wasteland” outside resolves into infrastructure. That change of eye is, in miniature, what the 2023 inscription asks of everyone.
